Description

CVM-A1500 is a panel mounted power quality analyzer with EMS (Energy Management Software) integrated. Its internal Web Server (html5) allows any user to have full installation control by using any web browser.

Designed to be installed in the most relevant or critical part of electric installations since it registers and monitors a wide range of variables (almost one year of data with RMS, maximum and minimum values). The device also registers power quality events such as swells, dips, interruptions (every half cycle) and transients (according to IEC 61000-4-30 Class A). Any event will be immediately captured with the voltage and current waveform.

This model adds the measurement of power quality variables (defined in the standard EN 50160) such as flicker, unbalance (Kd) and asymmetry (Ka) coefficients or voltage and current harmonics decomposition up to 63rd. In addition, it is possible to monitor in real time the instantaneous waveforms of voltage and current through its oscilloscope function.

As an added value, CVM-A1500 displays the number of events and transients on each affected phase with the level reached, duration and its associated waveform. In addition, those events are directly displayed in CBEMA, ITIC, and SEMI-F47 graphs.

The smart design of the CVM-A1500 allows users to customize their own screens in order to access the information faster and easier. Remark that the device allows connection through PowerStudio software to save and store, in a redundant way, all the information in a server or PC, avoiding memory limits.

Applications

Control, monitoring, and logging of the power quality in High and Low Voltage distribution panels. Performed directly or remotely thanks to its WEB server. Integration in SCADA systems through XML requests.

• 4 alarms (2 per transistor and 2 per relay), fully and independently programmable according to a low or high value, hysteresis, connection/disconnection delays, normally open or closed standby status, and interlocking.
• Generation of impulses with transistor outputs, fully and independently configurable over any incremental parameter (energy, costs, kgCO2, total meter, or tariff hours).
• Transducer converting analog signals to any instantaneous parameter measured or calculated by the unit, with built-in expansion modules with analog outputs.
• Display of process signals featuring a built-in expansion module with analog inputs, with optional reporting of these signals to SCADA systems through communication systems.
• Control of electrical load or alarm signal operations by programming the transistor or relay outputs that are built-in or added through expansion modules.
• Datalogger integrated with Web server and XML (log of historical data).
